What Is Mold Infographic

For more than a decade, mold has been in the news.
People are talking about the effect on population health
and damage to the building. But what are the risks and issues?
A number of agencies have guidelines that include protective
measures for mold remediation and cleaning.

There continues to be considerable scientific advances on the effects of molds and established links to potential health effects. The U.S. Centers for Disease Control and Prevention (CDC), National Academy of Medicine (NAM), World Health Organization (WHO), and Health Canada, all agree exposure to mold in buildings increases the risk of respiratory disease. Although there are no universally accepted standards for safe mold levels in indoor environments, several guidance documents exist.

Mold sensitivities vary from person to person, and individual differences play a significant role in the type and severity of symptoms experienced. AIHA provides comprehensive remediation and control guidance, including inspection and sampling protocols in their Recognition, Evaluation, and Control of Indoor Mold, also known as the "Green Book." This includes visual inspection techniques, air sampling methods and interpretation, allowing for successful remediation, and the ability to assess hidden contamination.

A complex problem

Communicating the health risks of mold to the public remains a complex problem for the scientific community. The truth is simpler solutions are easier to understand. Media attention on this topic creates emotionally charged circumstances. This renders professional judgment and reasoned dialogue challenging. In some instances, building owners often ignore or dismiss potentially serious problems. Seldom do buildings have just one problem, and many indoor air quality (IAQ) problems are not mold related. This makes communicating risk difficult.

Practical resources for the public

The resources offered below provide practical information from experienced AIHA professionals and volunteers. While not an exhaustive repository, this information is best used in conjunction with other guidance documents, and professional judgment by qualified consultants and public health officials. Mold prevention is the challenge of making tough and often costly decisions with limited or evolving information.

Information & Resources

When significant mold contamination is apparent, it is recommended to seek professional guidance before attempting to clean large amounts of materials greater than ten (10) square feet. Industrial hygienists and safety and health professionals can utilize AIHA resources to anticipate concerns and design solutions. Governmental guidelines and certifications, like those from the Institute of Inspection Cleaning and Restoration Certification (IICRC), offer crucial support and standards for the restoration industry.

The following agencies and organizations have guidance related to mold response:

The Centers for Disease Control and Prevention

Federal Emergency Management Agency

Canadian Centre for Occupational Health and Safety

U.S. Environmental Protection Agency

U.S. Occupational Safety and Health Administration

For IH/OEHS and IAQ professionals, the updated "Green Book" is available.

After external peer review, the AIHA Recognition, Evaluation, and Control of Indoor Mold, 2nd (2020) is now available. The new edition offers expertise from industrial hygiene practitioners, academics, government officials, and scientists.
